97% of readers write client-side code, while 56% said they write server-side code. Last year server-side development was at 28%. I'd like to think that the interest and adoption of technologies like Node will contribute to the direction of ECMAScript, because some proposals seem to go against the strides that have already been made in the Node community (the module system, for example).
The DailyJS readership is very experienced (27% said 5-10 years), so perhaps I should do more to cover advanced topics?
ES6 features are getting popular: 24% said they use ES6. I suspect that more people actually do use them, because
Testing: 29% said they write tests. I was interested to see that PhantomJS is a very popular test environment (38%). I've mentioned many times on DailyJS that I struggle a little bit when it comes to this type of testing, because the tests seem to become brittle and break over time. However, the number of people that use PhantomJS is close to Node, so presumably most people have found a way to make it work well enough.
Jasmine and Mocha are still the most popular test frameworks, and Karma is gaining on them now as well.
Gulp (35%) is already almost as popular as Grunt (47%). It's amazing how quickly Gulp has been adopted, although I've found I can understand Gulp more readily than Grunt scripts.
When it comes to client-side dependencies, CommonJS with Browserify is at 20%, with plain old files at 30%. I think that's interesting because Browserify is my preferred solution, but I often use plain old files because I'm working on a legacy project where Browserify is a luxury we don't have time for.
SublimeText won the editor wars, although a fair few readers use IDEs like IntelliJ and Visual Studio.
The most popular minimum IE is IE 9. I find that's interesting because I still get asked to support 8 for corporate networks that can't seem to untangle themselves from web-based legacy software (do any readers use ADP for example?)
Here are the top "other" programming languages:
I still find it strange that PHP is so popular, although it's 6 on the TIOBE index, and this is primarily a web development blog after all.
Thanks to everyone who took part in the survey! If you'd like me to run another rather than waiting for a whole year, then get in touch with your ideas.
